A cone is a three-dimensional figure that consists of a circular base and a curbed lateral surface that connects the base to a single point not in the plane of the base, called the vertex.

surface area of a cone- S=(pi)rl+(pi)r^2 OR S = L+B (L is lateral Base and B is base of area)

Volume of a cone- V=1/3(pi)^2h OR V= 1/3 Bh

Surface Area of A Right Cone: S = L + B or S = (pie) r l + (pie) r [squared] - The surface area, S, of a right cone with lateral area L, base of area B, radius r, and slant height l
